6 Claims.
The present invention relates to improvements in box-magazines and more particularly to improvements in multi-compartment box-magazines for firearms.
One of the objects ofthe present invention is to provide a superior multi-compartment boxmagazine which is readily shifted to bring either of its cartridge-compartments into cartridgefeeding relationship with respect to a repeating firearm.
Another object of the present invention is to provide a superior plural-compartment box-magazine in which two compartments are so related with respect to each other that when one there of is in position for feeding cartridges to a firearm, the other compartment is in position where by its loaded or empty condition may be ascertained at a glance.
With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art.
In the accompanying drawings, in which certain modes of carrying out the present invention are shown for illustrative purposes:
Fig. 1 is a view in side elevation of a repeating firearm equipped with a multi-compartment magazine embodying the present invention;
Fig. 2 is a broken view partly in side elevation and partly in central-longitudinal section of the portion of the automatic firearm adjacent the magazine-receiving opening therein and showing the mum-compartment box-magazine in section;
Fig. 3 is a broken sectional view taken on the line 33 of Fig. 2;
Fig. 4 is an end view of the magazine detached;
Fig. 5 is a view in side elevation of the magazine detached;
Fig. 6 is a transverse sectional view taken on the line 56 of Fig. 5; and
Fig. 7 is a perspective view of the magazine viewing the same partly from below.
The particular multi-compartment box-magazine herein chosen for purposes of illustrating the present invention, includes two vertical parallel cartridge-compartments I0 and II each preferably formed of sheet metal transversely folded into box-like form to provide a substantially-fiat inner wall I2, integral complemental side-walls I3-I3 and two laterally-spaced-apart integral outer-wall panels I I-I4 each respectively turned inwardly from one of the side-walls Iii-I3 toward the other side-wall. Formed integral with i and respectively extending outwardly from the inner edge of each of the outer-wall panels III-I 4 is one of two laterally-spaced-apart parallel side-wall panels I5--I5 each formed at its outer end with one of two reversely-bentbeads Iii-I6.
The side-wall panels I 5--I5 above referred to extend from the bottom of each vertical cartridge-compartment Ill and II to a point short of but adjacent the upper end of each of said compartments. The outer-wall panels I I-I4, however, extend substantially the full length of each compartment.
Spanning the gap between each pair of complemental side-wall panels I5-I5 above referred to and embracing the respective beads Iii-I6 thereof is a separately-formed outer wall I! which may be conveniently formed of sheet metal. The said outer wall I I is of a length substantially corresponding to the lengths of the complemental side-wall panels I5I5 to which it is rigidly attached by crimping.
The space between the laterally-spaced-apart side-wall'panels I5I5 of each cartridge-compartment II) and II provides a channel or runway for an actuating-finger I8 formed integral and bent rearwardly from a follower I9 which may be conveniently formed of sheet metal and which is of inverted U-shaped form. The said actuating-finger is designed to actuate a boltlock device employed in many types of firearms and not requiring detailed description or illustration herein.
Fitting within each of the cartridge-compartments I0 and II is one of two corresponding magazine-springs 20 thrusting at one end against the under face of its complemental follower I9 and thrusting at its opposite end against the inner face of a bottom-plate or end-wall 2|, one of which is removably installed in one end of each of the cartridge-compartments I0 and II.
Each of the side-walls I3--I3 of each of the cartridge-compartments I0 and II is bent inwardly towardthe complemental side-wall to provide oppositely-inclined cartridge-retaining lips 2222, the respective under faces of which are alternately engaged by one of a series of cartridges being raised by the follower I9 under the urge of the magazine-spring 2|]. The particular box-magazine shown is adapted to contain two columns of cartridges such as the cartridges 23 and each follower I9 is bent or otherwise provided with a cartridge-positioning lug 24 which serves to laterally displace the first cartridge entered into the given magazine-compartment, toward one side of the said compartment 50 that the next cartridge will in turn engage with the opposite wall of the compartment in a manner common in box-magazines. The inner wall I2 of each cartridge-compartment I and II at the end thereof adjacent the cartridge-retaining lips 2222 is bent or otherwise curved slightly outwardly to provide a stop-lip 25. The stop-lip 25 of each cartridge-compartment overhangs the bottom-plate or end-wall 2| of the complemental cartridge-compartment and is adapted to engage with a downwardly-facing stop-abutment 26 formed in a firearm-receiver 21 immediately forwardly of the magazine-receiving passage 28 formed in the lower wall of the said receiver, as
is particularly well shown in Figs. 2 and 3. The
said magazine-receiving passage 28 extends lengthwise of the receiver 21 only a distance corresponding to the horizontal length of but one of the vertical cartridge-compartments ID or II, The stop-lip 25 of each cartridge-compartment also serves to facilitate the manual installation of cartridges into its complemental cartridgecompartment during the magazine-loading operation.
The outer wall I! of each of the cartridgecompartments I0 and I I is formed with a latchreceiving opening 29 and is adapted to have its outer face bear against the forwardly-facing rear wall 35 of a vertical magazine-guiding groove 31 formed in the receiver 21 to the rear of the magazine-receiving passage 28 therein. The groove 3| just above referred to is formed partly in the receiver 2'1 proper and partly in the forward portion of an integral lug 32 depending from the said receiver, as is shown especially well in Fig. 2. The latch-receiving opening 29 in each of the outer-end walls I! is adapted to receive the forward end of a horizontally-reciprocating magazine-latch 33 movable in a forwardly-opening pocket 34 formed in the lug 32 and opening at its forward end into the vertical magazine-guiding groove 3|. The said magazine-latch is constantly urged forwardly into latching position by a helical latch-spring 35 thrusting forwardly against the said magazinelatch 33 and rearwardly against the integral endwall of the pocket 34. The lower forward portion of the magazine-latch 33 is formed with a rearwardly-and-downwardly-inclined bevel 36 to enable the said magazine-latch to be cammed rearwardly by the engagement of the upper edge of the outer wall ll of either magazine-compartment I0 or II, with the said bevel 36 of the magazine-latch. The magazine-latch 33 is adapted to be manually retired rearwardly to release the magazine, by means of a latch-operating lever 31 pivotally mounted in the lower portion of a vertical channel 38 formed in the lower end of the lug 32 and communicating at its upper end with the pocket 34 and at its forward end with the vertical magazine-guiding groove 3 I.
For the purpose of making the two complemental cartridge-compartments ID and II into a unitary structure, the respective abutting inner walls I2I2 thereof are preferably spot-welded as at 39 in several vertically-displaced locations, as shown in Fig. 2. Before being secured together into a unitary structure, the cartridge-compartments I8 and II are reversed one with respectto the other and then positioned in parallelism so that the bottom-plate 2! of each cartridge-compartment is displaced downwardly, so to speak, with respect to the adjacent cartridge-feeding end of the complemental compartment. The degree of displacement is such that when the cartridge-feeding end of one cartridge-compartment is inserted into the magazine-receiving passage such as 28, the bottom-plate 2I or its equivalent of the other cartridge-compartment will be below the portion of the receiver 21 lying forwardly of the said magazine-receiving passage 28 therein. The portion of each cartridge-compartment I0 and II which projects longitudinally beyond the end-wall 2I of the companion cartridg-compartment constitutes in effect a neckportion which, for convenience of description, is identified by the reference character 40.
The displacement of the respective cartridgecompartments I0 and II with respect to each other as above referred to, also serves to project the cartridge-delivery end of the particular cartridge-compartment not at the time in registry with the magazine-receiving passage 28, into position whereby the presence or absence of cartridges in the cartridge-delivery end of the nowinverted reserve cartridge-compartment, may be conveniently observed.
When the cartridges in one of the cartridgecompartments are exhausted, the multiple-compartment magazine may be detached from the firearm by manipulating the latch-operating lever 31 and inverted end-for-end by simple rotation in the plane of its normal position to project the cartridge-feeding end of the still-loaded cartridge-compartment into the magazine-receiving passage 28 of the firearm.
It is to be noted that the stop-lip 25 of each of the cartridge-compartments I0 and II in addition to acting as a stop to limit the penetration of its complemental cartridge-compartment into the cartridge-receiving passage 28 in the receiver 21. also acts in a funnel-like manner to assist in the guidance of cartridges being forced manually into the cartridge-feeding end of a cartridgecompartment, in the process of loading or charging the magazine.
The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
